From Solidsonline.com a great article by John Astad of the Combustible Dust Policy Institute, about burning the behavior of combustible dust.

Burning behavior (BZ) of combustible particulate solids is an important property. A property that is evaluated when developing engineering and administrative control measures for protecting the work-place from combustible dust fire and explosion hazards. Burning behavior can be as harmless as salt (BZ 1) or violent as black powder (BZ 6). Where does your dust fit between the two?
Knowing fire spread characteristics with BZ classification (severity of consequence) acquired from VDI 2263 test results assist safety professionals with developing a proactive housekeeping strategy. This strategy includes removing excessive dust layers from hard to reach and unseen overhead areas such as suspended ceilings, conduits, and structural girders. It is these overhead areas where fire can spread rapidl…

Recently a CSB recommendation in the Hoeganaes Case Study instructed OSHA to revise the Combustible Dust National Emphasis Program (NEP) to add industry codes for facilities that generate metal dusts (e.g., North American Industrial Classification System, NAICS, code 331111 Iron and Steel Mills, and other applicable codes not currently listed)..

What about the dozens of other NAICS having a history of combustible dust related fires and explosions that are not recognized in the ComDust NEP?
